Go Behind the Scenes with Ethan Zohn!

In his latest video, Ethan Zohn takes viewers behind the scenes at his PEOPLE photo shoot on Manhattan's West Side.

Diagnosed with Hodgkin's lymphoma last April – and after enduring three months of nausea-inducing chemotherapy last summer – the Survivor: Africa winner appears upbeat and filled with optimism at his photo shoot.

"Ethan was phenomenal," says his girlfriend of six years, fellow Survivor winner Jenna Morasca, 28. "He may have a career as a model – a bald model."

Zohn, who turned 36 on Nov. 12, is currently in the middle of a new treatment regimen aimed at wiping out the disease, which actually spread during the first chemo treatments.

After completing five weeks of daily radiation therapy, Zohn is expected to undergo a stem-cell transplant, during which he will remain hospitalized in isolation for 30 consecutive days. As he told PEOPLE with his trademark smile, "I'll officially be the Bubble Boy ... You've got to look around you, enjoy the little things and stay positive."
